Abstract
The utility model provides a water-pressure test unit for a large-diameter thick-wall pipe joint of a boiler-steam dome, which is used in a boiler manufacture industry. The water-pressure test unit comprises a sealing plate (1) and a sleeve pipe (2), wherein the diameter of the sealing plate (1) is the same as the inner diameter of the sleeve pipe (2); the sealing plate (1) is welded in the sleeve pipe (2) to form the cylindrical cap-shaped water-pressure test unit; and the inner diameter of the water test unit conforms to the outer diameter of the pipe joint (3). After the water-pressure test unit for the pipe joint is adopted, the water-pressure test unit can be conveniently disassembled during the test, the labor intensity of workers is greatly reduced, the work efficiency is greatly improved, and the water-pressure test unit has the advantages of reutilization and little material waste.
Description
Technical field
The utility model relates to the hydraulic testing field of boiler industry, and more particularly, the utility model relates to a kind of water test unit of boiler-steam dome major-diameter thick-wall pipe adapter.
Background technology
At present, the man boiler-steam dome major-diameter thick-wall of domestic most of boiler maker pipe adapter water test unit still adopts the mode of traditional vexed plate of welding to carry out the hydraulic testing.The cross-sectional view that is the device that adopts when carrying out the hydraulic testing of boiler-steam dome major-diameter thick-wall pipe adapter in the prior art shown in Figure 2.Because pipe adapter quantity is many on the boiler-steam dome, diameter big and thickness of pipe, adopt the pattern workload of the vexed plate of welding quite big, this test method is exactly at the trial, welds a plank in each pipe adapter exit, thereby reaches the effect with pipe seal.Because the quantity of pipe adapter is more on the boiler header, the workload of welding vexed plate is quite big, and the hydraulic testing also will be adopted the mode of gas cutting to cut vexed plate, and then carry out pipe adapter groove chamfering after finishing.Traditional test method is welded vexed plate only to utilize once, and the processing capacity of vexed plate is big and precision is high.Weld vexed plate and also must determine the pattern of the thickness and the welding joint of vexed plate according to the pressure of the hydraulic testing.Adopt the hydraulic testing labour intensity of this pattern, and waste of material is big, inefficiency, manufacturing cost is big, and the manufacturing cycle is long.
The utility model content
The utility model boiler-steam dome major-diameter thick-wall pipe adapter water test unit, its technical matters that will solve is: providing a kind of can effectively increase work efficiency, reduce manufacturing cost, reduce labor strength, obviously shorten the major-diameter thick-wall pipe adapter water test unit of test period.
The utility model is a kind of boiler-steam dome major-diameter thick-wall pipe adapter water test unit, and described pipe adapter water test unit comprises shrouding, and sleeve pipe, described shrouding become the water test unit of the cap-like structure of hollow with sleeve combination.
The diameter of described shrouding is consistent with the internal diameter of sleeve pipe, is welded in the sleeve pipe, thereby forms the water test unit of cylindrical cap shape.
The internal diameter of described water test unit matches with the external diameter of pipe adapter.
Described sleeve pipe edge is concordant structure.
After adopting pipe adapter water test unit of the present utility model, experimental provision convenient disassembly during test, and can reduce workman's labor operation intensity greatly, obviously improved work efficiency, and water test unit of the present utility model can be reused, and waste of material is few.
Description of drawings
Make briefly bright to each width of cloth accompanying drawing in this instructions expressed content and the mark among the figure below:
Fig. 1 is that cuing open of the utility model boiler-steam dome major-diameter thick-wall pipe adapter water test unit shown synoptic diagram;
Fig. 2 is the structure of available technology adopting;
Be labeled as among the figure: 1, shrouding; 2, sleeve pipe; 3, pipe adapter; 4, drum; 5, vexed plate; 6, fillet weld; 7, sleeve pipe edge
Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail embodiment:
As shown in Figure 1, the utility model is a kind of boiler-steam dome major-diameter thick-wall pipe adapter water test unit, it is characterized in that: described pipe adapter water test unit comprises shrouding 1, sleeve pipe 2, and described shrouding 1 and sleeve pipe 2 are combined into the water test unit of the cap-like structure of hollow.
The diameter of described shrouding 1 is consistent with the internal diameter of sleeve pipe 2, is welded in the sleeve pipe 2, thereby forms the water test unit of cylindrical cap shape.
The internal diameter of described water test unit matches with the external diameter of pipe adapter 3.
Described sleeve pipe edge 7 is concordant structure.
By above structure, just formed the pipe adapter jacket-type water test unit that can reach the hydraulic pressure plugging action.
During the boiler-steam dome hydraulic testing, adopt the form of fillet weld 6 to be connected with pipe adapter 3 pipe box 2, only need sleeve pipe 2 is worn with the weld seam that is connected 6 of pipe adapter 3 after the hydraulic testing, and pipe box 2 and pipe adapter 3 junctions be polished into the former state that rounding off just can recover pipe adapter 3.
Adopt pipe adapter jacket-type water test unit of the present utility model, its convenient disassembly, carry out the mode of the hydraulic testing compares with the mode that adopts the vexed plate of welding, greatly reduce workman's labor operation intensity after the hydraulic testing, obviously improved work efficiency, and water test unit can be reused, and waste of material is few.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasions without diverted via, all in protection domain of the present utility model.
Claims (4)
